格式SimpleDateFormat(“ HH.mm.ss”)显示时间。为了使用SimpleDateFormat类,我们导入了以下程序包。
import java.text.SimpleDateFormat;
在这里,我们使用SimpleDateFormat类显示日期和时间。让我们将其设置为所需的格式,即时间-HH.mm.ss-
Format f = new SimpleDateFormat("HH.mm.ss"); String strResult = f.format(new Date()); System.out.println("Time = "+strResult);
以下是一个例子-
import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { //显示当前日期和时间 Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MMMM/yyyy hh:mm:s"); System.out.println("Today's date = "+simpleformat.format(cal.getTime())); //当前时间 Format f = new SimpleDateFormat("HH.mm.ss"); String strResult = f.format(new Date()); System.out.println("Time = "+strResult); //显示小时 f = new SimpleDateFormat("H"); String strHour = f.format(new Date()); System.out.println("Current Hour = "+strHour); //显示分钟 f = new SimpleDateFormat("mm"); String strMinute = f.format(new Date()); System.out.println("Current Minutes = "+strMinute); //显示秒 f = new SimpleDateFormat("ss"); String strSeconds = f.format(new Date()); System.out.println("Current Seconds = "+strSeconds); } }
输出结果
Today's date = 26/November/2018 08:32:16 Time = 08.32.16 Current Hour = 8 Current Minutes = 32 Current Seconds = 16
